FURNACE-ARCH.

Speciflcati'on of Letters Patent.

Patented Feb. 17, 1920.

Application filed April 3, 1919. Serial No. 287,104.

To all whom it may concern:

Be it known that I, FRANK H. WAITE, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Furnace-Arches, of which the following is a specification. I

This invention has relation to the setting for steam boilers or the like, and has for an object to provide an arch for the combustion chamber of the boiler setting, said arch being composed of blocks of a specific construction to accomplish purposes and advantages hereinafter set forth.-

Another object of theinvention is to provide a specific construction in the arches of combustion chambers including arch blocks and a tubular member extending through each block and terminating in a bracket member for engagement upon a beam, whereby the block may be securely held.

Another object of the invention is to provide a block for chamber arches and boiler settings including a tubular member extending therethrough with a view to promoting the circulation of air through the .tubular member and to retain the block at as low a temperature as possible, said tubular member terminating in means engaging a support whereby the block may be securely held and relieved of strain.

In addition to the foregoing, this inven tion comprehends improvements in the details of construction and arrangement of parts, to be hereinafter describedand particularly set forth in the appended claim.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear,

Figure 1 is a view in section of a boiler setting illustrating the embodiment therein of my invention.

Fig. 2 is a view in rear elevation of a combustion chamber arch, and

Fig. 3 is a view in top plan of one of the blocks.

'With reference to the drawings, 10 indicates the back wall of a combustion chamher and 11 the boiler extending forwardly thereof. The arch of the combustion chamber is formed with a plurality of blocks indicated at 12, said blocks being square in cross section, although it will be understood that any variations in the dimensions may be made without departing from the spirit of the invention or the scope of the claim. Extending longitudinally of the block 12 from the point adjacent the rear end to a point approximating the opposite end is a tubular member or pipe 13. The forward end of the pipe 13 is engaged in an elbow coupling 14 which may be right angular or any angle desired, and extending upwardly from said coupling 14 is a short section'of piping 15. Connected to the upper end of said short section 15 is a T-coupling 16 having extended from opposite sides short sections of pipe 17 which are horizontal and substantially parallel to the section 13 although an angle between the twomaybe formed if desired or deemed expedient. It

will be noted that the rear end of the pipe section 13 is in communication with atmosphere eXteriorly of the block.

In use, one or more beams 18 are rested upon the side walls 19 of the boiler setting and extended transversely thereacross and beneath the sections 17 of the pipe support described above. In this manner the pipes are securely held and relieved of strain. It Will'be noted that to move one of the blocks without disturbing the remainder it is but necessary to rotate the coupling 16 'to dispose the pipe section 17 between the beams whereby the block may be lowered. Also, it will be noted that since the conibination of pipe sections is opened from end to end, the circulation of air there through is promoted and mal temperature and also y reason of high ermitted at nortemperatures within the combustion chamher. In this manner the blocks are retained at as low a temperature as possible thereby reducing the possibility of disintegration. Other uses and advanta es will readily occur to those skilled in th invention appertains.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claim.

art to which this Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

A furnace arch for COlI'lbllStlOIl chambers of boiler settings including supporting beams and arch blocks each of the latter 7 having a longitudinal channel and a trans verse channel intersecting the first channel, a tube located in the longitudinal channel having its inner end located at the point of intersection therewith of the transverse channel, a short section of tubing connected with the inner end of the first tube and located in the transverse channel with the opposite end of said short section extending 15 beyond the surface of the block, a third tubular section connected to said opposite end of the short section and resting upon the beams.

In testimony whereof I afiix my signature
